Abstract (en)

[origin: EP3624226A1] A separator for a lithium-sulfur battery including a separator base; and a coating layer present on one or more surface of the separator base, wherein the coating layer includes a structural unit (A) derived from one or more compound including (i) one or more group selected from the group consisting of a catechol group and a pyrogallol group, and (ii) one or more sulfonic acid group; and a structural unit (B) derived from dopamine, and wherein the coating layer includes a sulfonic acid anion group. Also, a lithium-sulfur battery manufactured using the same, and a method for preparing the separator.
